Example
Register a AnnotationTooltipCallback handler to show a tooltip for text annotations only.
NutrientViewer.load({
annotationTooltipCallback: function(annotation) {
if (annotation instanceof NutrientViewer.Annotations.TextAnnotation) {
var toolItem = {
type: 'custom',
title: 'tooltip item for text annotations',
id: 'item-text-tooltip-annotation',
className: 'TooltipItem-Text',
onPress: function () {
console.log(annotation)
}
}
return [toolItem]
} else {
return []
}
}
// ...
});
Type Declaration
Parameters
annotationAnnotationsUnion
The selected annotation.
Returns
ToolItem[]
This callback is called whenever an annotation gets selected and can be used to define and return an array of ToolItem that will be rendered in a tooltip for the given annotation.
If the callback returns an empty array then NutrientViewer won't show any tooltip for the selected annotation.
